ANTISLIPIING DEVICE.

To all whom it may concern:

Be it known that I, HARRY A. SARVER, a citizen of the United States,residing at Parkersburg,'in the county of Wood and State of WestVirginia, have inventedv certain new and useful Improvements inAntislipping Devices, of which the following is a specification,reference being had to the accompanying drawings.

This invention relates to certain improvements in anti-slipping devicesand has relation more particularly to a device of this general characterespecially designed and adapted for use in connection with the' wheelsof motor-driven vehicles; and it is an object of theinvention to providea device of this general character having novel and improved meanswhereby the same may be readily and conveniently applied intoo'penativeposition.

It is also an object of the invention to provide a novel and improveddevice of this general character comprising a plurality of operativelyconnected sections, each of said sections being provided with means toprevent slipping in either a circumferential or lateral direction. 1

The invention consists in the details of construction and in thecombination and arso rangement of the severalparts. of my improvedanti-clipping device whereby certain important advantages are attainedand the device is rendered simpler, less expensive and otherwise moreconvenient and advan- 85 tageous for use, all as will be hereinaftermore fully set forth.

The novel features of the invention will hereinafter be definitelyclaimed. In order that my invention maybe the better understood, I willnow proceed to describe the same with reference to the accompanyingdrawings, wherein Figure 1 is a fragmentary view in elevationillustrating an anti-slipping device constructed in accordance with anembodiment of my invention and in applied position;

Fig. 2 is a fragmentary view in plan of an anti-slippingrdevice asherein set forth; Fig. 3 is a agmentary view partly in elevation andpartly in section illustrating certain details of construction as hereinem: bodied;

trating afurther embodiment of my invention.

As disclosed in the accompanying drawmgs, my improved anti-slippingdevice includes a plurality of sections S adapted to extendlongitudinally in a direction circumferentially of the tread portion ofthe tire T of a wheel and which includesa centralelongated member 1disposed longitudinally on-a predetermined curvature and which isprovided-at its opposite ends with the outwardly disposed divergingextensions 2. The extensions 2 are also arranged longitudinally on apredetermined curvature so that when the section S is in appliedposition upon a tire, the elongated member 1 together with the branchesor extensions 2 will conform to the-peripheral configuration of the tireT.

The outer face'of' the elongated member 1 is provided with alongitudinally disposed calk 3 having its engaging edge disposed on acurvature substantially concentric to the periphery of the tire T,'saidcalk 3 serving to hold the wheel or tire against lateral slippingmovement or skidding. The member 1 is also provided at a pointsubstantially midway the length of'the calk 3 with the laterallydisposed supplemental calks 4 which serve'to prevent circumferentialslipping of the wheel or tire. I

The outer end portion of each of the branches or extensions 2 isprovided with an enlargement 5 with which is engaged a calk 6 preferablyin the form of a truncated pyramidand which serves to afford aneffective grippingaction especially when the wheel or tire is travelingover ice, snow, mud or the like.

The sections S are rigid and preferably formed of metal and adjacentsections S are connected one to the other through the medium of the tiemembers 7 and 8. As herein disclosed, each of the members 7 consists ofan elongated bar or rod 9 having its extremities in swiveled engagement,as at 10, with adjacent calks, 6 and provided intermediate its lengthwith an eye 11. Connected with the eye 11 is a flexible member 12suitably anchored to a Patented May 29, 1917.. Application filedNovember 25, 1916. Seria1 No.133,424.

flexible member 14 disposedv circumferentiallyof the tire of thecoacting rim R. The flexible members 14 are two in number and arrangedat opposite sides of the tire T or rim R and the extremities of each ofsaid members are suitably connected one to die other, as indicated at15, whereby it will be perceived that the sections S will be efiectivelyheld in applied position upon the tread portion of the tire T.-

The members 8 as herein in the form of a linked chain and having theirouter portions laterally disposed through suitable openings 16 in theadjacent enlargements 5. This 'form of connectingmember is affordedtopermit my improved anti-slipping device to beiolded or compacted tooccupy a minimum ofspace and which is particularly desirable when thedevice is not in use. Itis to be also noted that one of the intermediatelinks 11 serves as an eye with which a flexiblemember 12 may be engaged.

Certain of the sections S are capable of detachable connection one withthe other, as indicated at 17, so that the application of my improveddevice may be materially facilitated. a

In the form of invention illustrated in detail Fig. 5 it is to be notedthat the connecting bar or rod 9 is provided adjacent its opposite endswith the eyes 11 with each of which a flexible securing member isadapted to be engaged. I have found in practice that by providing eachbar or rod 9 with a plurallty of eyes 11 additional strength is affordedthe anti-slipping device.

'From the foregoing description, it is thought to beobvious that ananti-slipping device constructed in accordance with .my'

invention is of an extremely simple and comparatively inexpensive natureand is particularly well adapted for use by reason of the convenienceand facility with which it maybe assembled, and it will also be obviousthat my invention is susceptibleof some change and modification withoutmaterial departure from the'principles and sp1rit thereof and for thisreason I do not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice, except as hereinafter claimed.

I claim:

1. An anti-slipping device com rising a sections plurality of sections,each of sai including an elongatedmember provided embodied are withdiverging extensions adjacent its opposlte ends, sald member andextenslons being provided with calks, and means for connecting adjacentends of said sections plurality of connected sections adapted to bedisposed circumferentially of a tire, each of said sections including anelongated member provided adjacent its opposite ends with diverging.extensions, a longitudinally disposed calk carriedbythe member, and acalk carried by the outer, end portion of each of the extensions.

' 4:. An anti-slipping device comprising a plurality of connectedsections adapted to be disposed circumferentially of a tire, each ofsaid sections including an elongated member provided adjacent itsopposite ends with diverging extensions, a longitudinally disposed calkcarried by the member, a calk carried by the outer end portion of eachof the extensions, and means coacting with said last named calks forsecuring adjacent sections one to the other.

5. An anti-slipping device comprising a plurality of connected sectionsadapted to be disposed circumferentially of a tire, each of saidsections includin an elongated member provided adjacent 1t's oppositeends with diverging extensions, a calk carried by the outer end portionof each of the extensions, and means in swiveled connection with thevcalks for connecting adjacent sections. j

In testimony whereof I hereunto afix my signature in the presence of twowltnesses.
